Dmitry Rybolovlev went into business with his scientist father in 1990 after studying medicine at Russia's Perm Medical Institute. In 1992, he opened an investment fund and, like other future tycoons, began buying shares of industrial enterprises. He consolidated his shares into a controlling stake and in 1995 was named chairman of the board of Uralkali, Russia's largest producer of potassium fertilizers. The company listed in London in 2007, raising $1 billion. Rybolovlev sold his stake for $6.5 billion in 2010. He is best known in the U.S. for his real estate moves. He bought Donald Trump's Palm Beach mansion, Maison de L'Amitie, for $95 million in 2008. He also apparently paid more than $300 million for La Belle Epoque penthouse in Monaco, where he lives. (His daughter Ekaterina bought Skorpios, the Greek island that belonged to successors of Aristotle Onassis, in 2013 and owns a New York City apartment, for which she paid $88 million). Rybolovlev also owns the the AS Monaco football club. In 2014, a Swiss court ordered Rybolovlev to pay $4.5 billion to his ex-wife, Elena, after a seven-year divorce battle. The billionaire appealed, and in June 2015 the court reduced the sum to $605 million. In October 2015, Rybolovlev and his ex-wife reached an undisclosed settlement, and she withdrew her claims.
